operation

1. This heater must be properly installed before it is used.
2. Prior to energization remove all construction dirt (plaster,
sawdust, etc.) from interior and exterior of heater.
3. Adjust thermostat with screwdriver. This unit is also
controllable from a line voltage wall thermostat or field
installed built-in tamperproof single or double pole
thermostat kit.
Dimplex kickspace heaters are designed and tested for safe
and trouble-free operation. All Dimplex kickspace heaters
are protected against overheating by a built-in thermal cutout.
Free airflow throughout the heater is extremely important for
the most efficient operation of the heater. Restricted airflow
may cause the thermal overload protector to cycle the heater
"ON and OFF". A cycling heater will not supply sufficient heat
to the room.
Avoid direct contact of paper, fabric, or furniture with heater.
